Fig. 7: The tumor-infiltrated pattern in the TDLNs+ of LUAD.

Polarized pattern: A, B (10x); a-b (200X). Metastatic cancer cells infiltrated the TDLNs+ as cohesive clusters and displayed a polarized distribution within the TDLNs+. Scattered pattern: C, D (10x); c-d (200X). Metastatic cancer cells infiltrated the TDLNs+ as isolated nests or clusters and were randomly distributed within the TDLNs+. Red arrow: tumor cluster.
